Biofrontera AG: Biofrontera AG obtains notice of allowance for US patent on PDT-lamp and treatment method

Leverkusen (pta016/08.12.2021/13:25 UTC+1)

Leverkusen, Germany, December 8, 2021 – Biofrontera AG (NASDAQ: BFRA; Frankfurt Stock Exchange: B8F), an international biopharmaceutical company, announces that its wholly owned subsidiary Biofrontera Pharma GmbH has received a notice of allowance from the United States Patent and Trademark office (USPTO) with respect to the patent application "Illumination device for photodynamic therapy, method for treating a skin disease and method for operating an illumination device" (US 17/215,785), which protects a number of innovations in the recently FDA-approved RhodoLED XL lamp.

"The technical improvements claimed in the patent allow for increasing standardization and procedural compliance for photodynamic therapy (PDT) with Ameluz in combination with the new RhodoLED XL lamp, which ensures patient safety and efficacy", explained Hermann Lübbert, CEO of Biofrontera AG. "Together with last week’s patent granted, which we announced on Dec 2, these patents jointly serve as an important step in strengthening the competitive advantage as well as the protection of Ameluz® and the RhodoLED lamp series as part of the FDA-combination approval."

The patent application describes specific features of the LED arrays of the five panels constituting the lamp head of the RhodoLED XL. The improved spatial LED arrangement optimizes the homogeneity of the illumination. The patent further describes the implementation of a distance sensor in each panel that improves positioning of the device: The sensors are connected to visual feedback mechanisms that support the operator in properly positioning all five panels at the recommended treatment distance. This increases standardization of the illumination and ultimately contributes to patient safety, while facilitating handling of the lamp for the treating physician.

This application constitutes a continuation-in-part of the US application US 17/071,496, and thus claims the same priority date of October 15, 2020. The continuation-in-part had been filed as a fast-track application on March 29, 2021 and an allowance was achieved in less than 9 months. A worldwide application based on this invention and claiming the same priority date has also been filed (PCT/EP2021/078045).
